COMBINEDYlS E AND LATHE.

SPECIFICATION forming part of Letters Patent No. 292,342, dated January 22, 1884. Application filed August 20, 1883. (No model.) i

To all whom it may concern.-

Be it known that I, JAMES R. MOMILLAN, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Combined Vise and Lathe, of which the following is a specification.

One object of my invention is to so construct I or other suitable fastening device. (See Figs.

1 and 5.) The spindle has a ratchet-wheel, g, and hung to the spindle is a lever, g, which carries a spring-pawl, g, acting on the ratchet-wheel. Above the pawl is a shaft, h, havupon the pawl so as to lock the same to the wheel 9, in which case the lever serves as a mg a cam, h, which can be caused to bear a vise that it can be used as a lathe or boring machine, a further object being to insure a firm grip of the jaws of the vise on the work.

handle by which the spindle D can be turned in either direction, the pawl acting in theusual manner under control of the spring when These objects I attain in the manner hereinafter set forth, reference being. had to the accompanying drawings, in which- Figure 1 is a longitudinal section of my improved vise; Figs. 2, 3, and 4, transverse sections, respectively, on the lines 1 2, 3 4c, and 5 6, Fig. 1;v and Figs. 5, 6, 7, 8, and 9, de tached views of parts of the vase.

A is the fixed stock of the vise, and B the movable stock of the same, the stock A being bolted to a bench or other support, and the stock B being guided upon the projecting stem A of said stock A, in the usual manner.

D is the screw-spindle of the vise, which is fitted snugly to, but canturn freely in, longitudinal openings in the two stocks, and is also adapted to a nut, F, fitted to a recess inthe stock B, and capable of being locked to or released from said stock by means of an arm, a, on a rock-shaft, b, the arm being adapted to bear upon a flattened portion of the nut, as shown in Fig. 4, and the shaft being free to turn in bearings in the stock B, and being provided with a handle, d, so that the arm can be caused to engage with and retain the nut, or can be thrown down, so as to free the same and permit it to turn with the screw-spindle.

Other forms of locking and releasing devices for the nut canbe used in place of that shown, the loose nut being a common feature in some Vises, for the purpose of permitting the ready adjustment of the movable stock of the work prior to the clamping of the latter.

The screw-spindle is confinedlongitudinally to the stock A by an arm, f, pivoted to the stock at its lower-end, adapted to engage with a grooved collar, f, on the spindle, and provided at the upper end with alocking-pin,f

the cam h is lifted. The shaft It has a milled head, It", by which it can be readily manipulated.

Beneath the stem A slides the horizontal cally to the stem by means of a bolt, t, and nut, i, the bolt being adapted to a slot, in the frame, so that the latter can be adjusted longitudinally in respect to the stock A. The

gearingj, the spindle I being in line with the screw-spindle D, and the spindle J in line with a fixed center pin or stud, J, secured to the stock 13 of the vise. screw-spindle D has a socket for the reception of a drill or other tool, and the nut F projects beyond the rear face of the stock B, and has a flange, k, which can be grasped by the hand,

shown in Fig. 6, for instance-in order to re turn the nut when it is released from the control of the arm a, as described hereinafter. The outer end of the spindle D also has a socket for the reception of a suitable tool. F has a slight longitudinal play in the recess of the stock B, and 011 the operation of the screw-spindle the first effect of the movement is to draw the nut forward in the recess.

stock B, is a cam-lever, L, the long arm of which bears upon the front edge of the nut, and is held in contact therewith by a spring, 12, the short arm of the lever being forked, and

arm A of the fixed stock of the vise. It will thusbe seen that the first movement of" the screw-spindle D causes the nut to act on the portion of a frame, G, which is secured vertiouter portion of the frame is vertical, and carries two spindles, I and J, connected by spur- The inner end of the or by a friction clamping devicesuch as The nut 8 5 Hung to the shaft 12, which is carried by the bearing upon-the bottom of the recess in the lever L and the latter to bind on the arm A, so as to tip up the rear end of the stock B and throw the upper part of the jaw .2: of the same toward the jaw w of the stock A. By this means I overcome the tendency which ordinary vises have to spread apart at the top of thejaws, where most of the work is held.

The tipping of the stock implies a loose fit of the guides of the same; but this is almost always the case after the vise has been in use for a time, and the movement of the lever L is adjusted, as described hereinafter, to accord with this loose fit.

A spring-ring, s, bears upon the front edge of the nut,- and serves to prevent any rattling or loose movement of the stock B, the tension of the spring being less than the effort required to move the stock B by the nut, sothat the lever L will always be actuated before the stock is moved forward. Set-screwstarc car ried by the stock B, and in the present instance adapted to recesses in the ring. (See Figs. 7 and S.) The nut, in its forward movement, acts upon the lever L until the nut comes .into contact with the heads of these setscrews, when the movement is transmitted to the stock B and further operation of the lever L is prevented, said lever sliding with the stock.

By adjusting the set-screws t the amountof pressure imparted to the lever L before the movement of the stock B commences can be readily varied.

In using the vise the screw-spindle isconfined longitudinally to the stock A by the arm f, the nut F is locked to the stock B by the arm a, and the lever r/ is secured to the spindle D by the action of the cam 71 on the pawl 9". The vise thus works the same as an ordinary vise.

Ordinary wood-turning can be accomplished by securing the object to the spindle J, which is driven from the spindle I, the latter being turned by hand or by a belt adapted to the pulley I.

Vhen it is desired to use the screw-spindle D of the vise, in connection with the spindle I, for drilling, boring, or other work, the stock B is first closed against the stock A, and secured in this position by a set-screw, m. The screw spindle D is then released from the stock A by retracting the arm f, and the nut F is freed from the stock B by depressing the arm a, the spindle being then drawn out to its full extent. The spindle is now at liberty to be rotated by the lever either continuously if the pawl is locked to the ratchet, or intermittently if the pawl acts upon the ratchet, as usual, the work being held in a chuck, K, on the spindle I, which can be turned backward, if desired, or may be prevented from turning by a suitable transverse pin, a, as shown by dotted lines in Fig. 1. Where a drill is being used, the proper feeding of the same is effected by the friction exerted upon the flange 7., either by hand or by the friction clamping device, Fig. 6, the spindle being caused to move rearward as it is rotated so long as the nut is prevented from turning.

\Vhcn it is desired to work a drill or boringtool without releasing the spindle D from its longitudinal connection with the stock A, I use the attachment shown in Fig. 9. This consists of a sleeve, I, carrying a drill-chuck, and having a spline, 10, adapted to a slot cut in that portion of the screw-spindle which projects beyond the stock B when the latter is closed against the stock A.

To the spindle D is fitted a clamp-nut, S, similar to that shown in Fig. 6, this nut bearing upon the inner end of the sleeve, as shown in Fig. 9. hen the spindle is rotated, the sleeve 1 will rotate therewith, owing to its spline w, and as long as the nut S is permitted to rotate with the spindle there will be no feeding of the sleeve and its drill; but if the nut is prevented from turning, there will be a movement of the same on the spindle and a corresponding movement of the sleeve, as will be readily understood.
